BT Broadband Talk

Does anyone have a working sip configuration to use BT Broadband Talk with asterisk?

seems to be conflicting info about this : … 6?thread=7 … umpost1419

although my thinking is “why the heck would you want to ?? there are much better deals to be had elsewhere.”

It comes free with my broadband access so might as well use it. Would never pay for it seperatelly tho.
